Valeriana locusta,[1] commonly called mâche, cornsalad, or lamb's lettuce, a small, herbaceous, annual flowering plant in the honeysuckle family Caprifoliaceae.

[11] It was grown commercially in London from the late 18th or early 19th century and appeared on markets as a winter vegetable, but it only became available in modern supermarkets there in the 1980s.

[12] American president Thomas Jefferson cultivated mâche at his home, Monticello, in Virginia in the early 1800s.

The common name 'cornsalad' refers to the fact that it often grows as a weed in cornfields[11] ('corn' is used in the sense of 'cereal', not the US meaning of maize).

In some areas of Germany it is known as rapunzel, and is the origin of the long-haired maiden's name in the eponymous fairy tale.

Like other formerly foraged greens, cornsalad has many nutrients, including three times as much vitamin C as lettuce, beta-carotene, B6, iron, and potassium.
